To all whom it may concern:

Be it known that I, CALVIN H. WESTON, of Tyrone, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvement in Physicians' Treating-Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in. physicians treating tables, especially designed for use by osteopaths, electrical practitioners and mechanical therapeutists, for the purpose of treating patients by either electricity or by moving and stretching various parts of the human body or by both.

The primary object of my invention is to provide a table of the class mentioned embodying mechanisms, which with easy manipulation and control imparts a multiplicity of movements to a movable part of the table, whereby the correcting and curing of physical defects of the spine and the like is eii'ected and I combine with this mechanism an electrical appliance which may be used either with the mechanism or without the same.

To accomplish these objects I provide a table which consists of a stationary member, a movable member pivotally connected thereto for universal movement, and means for looking said movable member laterally, swinging it vertically or laterally relative to the stationary member, rocking it laterally and swinging it laterally in a universal movement, or swinging it laterally and vertically in a different universal movement.

XVith these and other objects in view my invention consists in the novel features hereinaftcr described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Referring to said drawings,-Figure 1 is a side View of my improved table. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal vertical sectional view. lh'g. 4 is a longitudinal horizontal sectional vew taken just below the table top. Fig. 5 is a diagrammatic view of the table and electrical appliance wiring. Fig. 6 is a perspective view of the extensible portion of the table designed to increase or decrease the length of said table. Fig. 7 is a top plan view of the extensible portion of the table and a horizontal sectional view of the table proper, showing the means for securing the extensble portion of the table in the movable portion. Fig. 8 is a vertical sectional view of a detail showing one of the table arms. Fig. 9 is a detail perspective View of one of the table arm hand plates. is a detail showing the connection between the slide rocking lever and the oscillating pivot post shoe track. Fig. 11 is a detail vertical sectional view of the pivot post, its shoe and the oscillating tracks for the postshoe. F ig. 12 is a detail perspective of the pivot post shoe. Fig. 13 is a detail perspective of a bracket used upon one of the links which connect the slotted rocking lever and the pivot post for the purpose of raising one of the adjacent link ends smultaneously with the first named link. Fig. 14 is a detail showing the limb clamp for securing the legs of the patient to the table. Fig. 15 is a diagrammatic View of the table top, showing in dotted lines the vertical Swinging of the movable part of the table. Fig. 16 is a detail showing a modification of one of the controlling treadles and its ratchet lock, the ratchet being shown in locked position. Fig. 17 is a similar view showing the ratchet in unlocked position. Fig. 18 is a detail perspective of one of the adjustable shoes used in connection with the electrical appliance. Fig. 19 is a diagrammatic view showing the lateral rocking movement of the movable member of the table. F ig. 20 is a similar view showing the lateral swinging movement of the movable member of the table. Fig. 21 is a sinilar View showing the vertical swinging movement of the movable portion of the table. Fig. 22 is a similar view of one of the universal movements of the movable parts of the table, said movement combining the two movements shown in Figs. 20 and 21. Fig. 23 is a similar view showing the universal movement obtained by combining the two movements shown in Figs. 19 and 20.

Referring particularly to the characters of reference upon the drawings, 1 designates the stationary or fixed portion of the table which is suitably supported by means of a framework 2 consisting of rods and bars 2 2, 2 and 2 all of which is in turn carried by the table legs 3. This framework is Fig. 10

preferably composed of metal and is inclosed in a casing 4 which is inclined at one end to allow the movable part of the table hereinafter described to swing vertically.

The fixed member 1 is provided at one end with apertured lugs 5 loosely carrying a disk 6 therebetween, by means of a pin 7 and a movable part 8 of the table is loosely connected for oscillation on a bracket post 9 having arms 10 provided with extensions 11, which. are loosely mounted in apertures (not shown) in said disk 6 whereby the two parts of the table are swiveled for universal movement. Ri 'dly connected to said arms 10 by means o rods 12 is the pivot post 13 which extends upwardly from the bars 2 of the framework.

Mounted in bearings 14 carried by the framework 2 beneath the movable part of the table is a shaft 15 carrying upon its extremities sprockets 16 and provided intermediate its ends with a rigidly mounted eccentric wheel 17, whose periphe'ry is provided with a freely mounted hub 18, which in turn is rigidly connected to one end of a beam 19 formed of two parts which extend around the pivot post 13 and terminate at their outer ends in a pivot connection 20 on a slotted lever 21, the slotted lever being pivotally connected to the framework by means of the pintle 22. It will be apparent from the foregoing that upon the shaft 15 being rotated through the chain 15 from the motor 15 carried in brackets on the under side of the stationary portion 1 of the table, that the eccentric wheel 17 will impart a reciprocating motion to the beam 19 and said beam will oscillate the lever 21 upon its pivot 22.

The pivot post 13 comprises a square pin 13 which extends through a two part casing 13 and 13 and is pivotally connected at its lower end to the shoe 23. The two parts 13 and 13 of the casing are suitably connected together and carry a freely rotatable collar 13 and a freely connected collar 13 as best shown in Fig. 11, and a brace 13 extends from the parts 13 of the post 13 to the movable portion of the table 8, to which it is connected by universal joint 13 The shoe 23 is provided upon the lower end of the square rod 13' of the post in a swiveled manner and is adapted to slide in a track 24. Said track is provided on its under surface with a stud 25 that extends through an aperture formed between two of the bars 2 of the framework and is provided with a Washer 26 which is held upon the stud and secures the track in a pivotal manner between the beforementioned bars 2 by means of a nut 27. This mounting' of the track 24 allows the same to oscillate horizontally for the purpose of turning the post 13 when said track is actuated by means hereinafter described. The rigidly connected collar 13 of the post 13 is provided with laterally extending arms 28 and one of said arms is pivotally connected by a uni- Versal joint 30 with one end of a link 29 which extends from said arm 28 to the slotted lever 21, where it terrhinates in a stirrup `31 which is mounted to slide on one of the bars of the slotted lever.

For the purpose of changing the leverage between the slotted bar 21 and the arm 28 to which the link 29 is connected, I provide a block guide 32 longitudinally movable upon said link 29 and connect said guide up with a rock shaft 33 by rods 34 which are rigidly connected to said rock shaft and pivotally connected to said block guide. Said rock shaft 33 extends outside of the casing '4 and is provided with a treadle 35 adapted to be operated by the physician for the purpose of raisng the link 29, so that when motion is transmitted to the slotted lever 21 it will be imparted also to the arm 28 to which the link 29 is connected. For the purpose of loclcing the said lever or treadle 35 in a de:

sired position to obtain more or less leverage in the link 29 I provide a curved rack 36 having teeth with which the lever or treadle 35 engages in a frictional manner. The arms 28 are also pivotally connected at 28 with vertical telescopic links 37 whose upper ends are pivotally connected at 37 to bell crank levers 38 carried by brackets 39 secured to the stationary portion of the table. Brackets 40 are rigidly connected to the underside of the movable portion of the table and these brackets are pivotally connected at 41 to horizontally disposed telescopic links 42 which are also connected to the bell cranks 38. It will be noted at this point, that the links 37 and 42 are made telescopic to allow the movable part 8 of the table to be moved in a number of different directions, which would not be permissible were solid links used.

From the foregoing it will be seen that when the link 29 is raised by means of the treadle 35, upon the slotted lever 21 and motion is given to said lever 21 by the motor and their connecting parts that the arms 28 will be swung horizontally, using the post 31 as a fulcrum and consequently the links 37 on the opposite side of the post will cause the bell crank 38 to operate the links 42 in opposite directions and cause the movable portion 8 of the table to be rocked laterally as shown in Fig. 19, using the bracket post 9 as a pivot.

A link 43 is pivotally connected to the collar 13 upon the post 13 by means of a universal joint 44 and the opposite end of said link is provided with a stirrup 45 which also slides upon the slotted lever 21. The end of the link 43, which is connected to the slotted lever 21, is moved vertically relative to said lever for operation on the post 13 by means of a guide block 46 which is loosely mounted on said link 43 and is actuated by means ofa rock shaft 47 through connecting rods 48 rigidly connected to the rock shaft 47 and pivotally connected to said guide 46.

The rock shaft 47 is controlled by'means of a treadle 49 and this treadle is also held in adjusted position by means of a circular rack 50 and when said rock shaft 47 is operated to lift the end of the lever 43 relative to the slotted bar 21 and said slotted bar is oscillated by means heretofore recited, the link 43 will reciprocate the lower end of the post 13 and cause the movable portion 8 of the table, through the medium of the bracket 13 to Swing said movable' portion of the table Vertically, as shown in Fig. 21, using the sides of the disk 7 in which arms 11 terminate, as a fulcrum.

It will be noted, that as this movement takes place the shoe 23 which is pivotally carried by the lower end of the post 13 moves in the track 24 and the vertical Swinging of the movable portion 8 of the table is materially assisted by springs 51, which are connected to said post and extends to and are secured to a stationary portion of the frame. It will also be observed that a bracket 52 is provided upon the outer end of the stirrup 45 and has a horizontally extending part 53 which engages the outer end of the stirrup 31, each time the link 43 is raised, for the purpose of obviating confusion of movement which might be caused when the movable part is operated to swing vertically.

An arm 54 is provided upon the oscillating track 24 and said arm is connected by means of a universal joint 55 with the inner end of a link 56, said link terminating at its outer end in a stirrup 57 which also slides on the slotted lever 21. A rock shaft 58 is connected up by means of rods 59 with a guide block 60 provided upon said link 56 for the purpose of raising the outer end of said link 56 and a treadle 61 is provided upon the outer end of said rock shaft 58 for Operating the same. Said treadle is held in adjusted position by means of a rack 62.

When the treadle 61 is moved by the operator, the rock shaft 58, through the links or rods 59, causes the outer end of the link.56 to be elevated and when said link 56 is reciprocated by means of the slotted lever 21 it will oscillate the track 24 and as said track is oscillated it will, through the medium of the square portion of the post 13 cause the movable portion 8 to be swung laterally relative to the stationary part 1 of the table as shown in Fig. 20 of the drawing. Should the links 29 and 43 be both raised at the same time as the link 56, a plurality of movements would be imparted to the movable part 8 of the table owing to the link 43 reciprocating the post and the link 56 oscillating the track 24 and this Would cause such a movement as is best shown in F ig. 22 of the drawing. Again, should the links 29 and 56 only be raised and the link 43' left in depressed condition, a different movement still will be imparted to the movable portion of the table, by reason of the link 29 through its connection with the movable portion of the table 8 causing said movable portion of the table to oscillate vertically on its pivot 9, and the track 24 through the medium of the link 56 swinging or turning the post 13 and causing the table to be swung laterally. This Will cause a combined laterally swinging and vertically oscillating universal movement as best shown in F ig. 23.

The stationary portion 1 of the table is provided on each of its lateral edges with a recess 63 in the Walls of which is pivotally mounted by means of the pivot pins 64 arms 65 which are adapted to support the arms of a patient lying upon the table when the table is in use, and to be folded into the recesses 63 when the table is not in use. Each of these arms 65 is provided with a slot 66 which extends through the arm and a depression 67 upon the upper portion of said arm, and hand plates 68 are mounted for sliding movement in said depressions and are provided on their under surface with studs 69 which extend through the slots 66 for the pur ose of making the hand plates laterally ad ustable. The stationary portion of the table is also provided with a slot 70 on either side of which tracks 71 are provided and in these tracks a carriage 72 is mounted.

`Pivotally mounted upon the upper surface of the carriage 72 is a suitably padded face mask 73 in which the patients face is adapted to rest when the patient is lying upon the table with his face downward. For the purpose of adjusting the face mask and carriage in the track 71 I have provided a screw threaded stud which carries a plate 75 that extends across the slot 70 and is held in engagement with the under surface of the part 1 of the table by means of a hand screw 76. It will, therefore, be seen that the face mask may be adjusted longitudinally of the table to accommodate patients of different heights and is also pivotally mounted to allow the patient to move hishead.

The movable portion 8 of the table is provided on its lateral edges with brackets 77 upon one of which a leg clamp 78 is swiveled and is adapted to be swung across said table and be secured to the opposite bracket by means of straps 79 having buckles 80. To lengthen the table I have provided an extensible portion 81 having posts 82 provided with notches 83 and mounted in circular apertures in the movable portion 8 of the table. Spring controlled latches 84 are provided for the purpose of preventing said eXtensible portion 81 from being withdrawn entirely from the table.

In Figs. 16 and 17 I have shown the rock shafts which control the link elevating mechanism as provided with ratchets 85 which may be locked by weighted pawls 86. This Construction may be used in lieu of the circular racks should it be desired. p

The entire foregoing is descriptive of the mechanical portion of my invention and in use a patient lies upon the table with his face downward, his headresting in the mask 73, his arms resting on the arms 65 and his legs clamped upon the movable portion 8 of the table by means of the clamp 78. When motion is imparte'd to the movable part 8 of the tableit is apparent that the patient s muscles would be stretched and then fiexed and by having a plurality of movements the table will more beneficially treat patients than those tables heretofore known.

Having described the mechanical construction of my invention I will now proceed to describe the electrical apparatus used in connection therewith. This electrical apparatus consists of the wiring diagrammatically shown in F ig. 5 in which the plus wire is shown as first passing through a controlling device 87 provided on the eXterior of the casing 4, thence through the motor 15 to a resistance 88 gvhich is suitably con trolled by means of a regulator 89 provided on the exterior of the casing 4. The plus wire then extends from the resistance 88 to two terminal hand clamps 90 which are adapted to be placed on the operator@ hands for manipulation upon the patient. The minus wire is provided with a.number of take off wires 93, 94 and 95, two of which are connected with the stud 69 on the hand plates 68, one of which terminates in a cap 91 and the remaining two terminate in adjustable shoes 92 which are adapted to be placed on the patient's feet. Upon the side of the casing 4 is mounted a bracket 96 which supports the patient@ head cap 91 when the same is not in use; also mounted on the side of thecasing 4 is a bracket 97 provided with a hook 98 upon which the hand clamps 90 may be hung, above the table, when the said hand clamps are not in use. It will therefore be seen that when power is admitted to the different wires that a circuit will be formed through the patient s body by the operator's hands contacting with the body of the patient, the electricity passing out the terminals formed at the head, hands, and feet of the patient. Should the motor controlling switch be turned so as to prevent the power from entering the motor it will be seen that the electricity will act only as an electrical treating medium for the patient but should the switch be turned so as to allow the power to enter the motor,

and either one of the foot treadles or the combinations of foot treadles be operated, then the table will be given movement.

By my improved device it will be apparent to those skilled in the art that I have devised a novel device which may be used either for mechanical treatment or electrical treatment or both simultaneously.

It will be evident that the adjacent ends of the fixed portion 1 of the table and the movable portion 8 may be made in any suitable configuration. Also adjustable means may be'provided for covering the space between the said portions 1 and 8 without departing from the spirit of my invention.
